SPECIFICATION forming part of Letters Patent No. 786,552, dated April 4,1905. Application filed August is, 1904.. Serial No. 221,209.

To aZZ whom it may concern.-

Be it known that I, MATTHEW DUFFNER, a citizen of the United States ofAmerica, residing at Allegheny, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements inExercising Devices, of which the following isa specification.

This invention relates to exercising machines or apparatus; and it hasfor its object a device of this kind that not only serves as anexerciser, but at the same time provides an electric current for theuser that greatly enhances the benefit of the apparatus.

Another object of theinvention is to provide means whereby the source ofelectricity is carried by the exerciser itself. It also provides meanswhereby easy access may be had to the said electrical source for thepurpose of recharging or removing.

Furthermore, it is the object of the invention to provide a device ofthis character that is portable-one that can be used attached to thewall, ceiling, or fioor, or any other suitable place.

Furthermore, the object of the invention is to provide a device of thekind that is simple and economical to manufacture.

With the above and other objects in view the invention consists in thedetails of construction and in the arrangement and combination of parts,to be hereinafter more fully described and claimed.

In describing the invention in detail reference will be had to theaccompanying drawings, forming part of this specification, wherein likereference characters will denote corresponding parts in the severalviews, and in which Figure 1 is a perspective view vention applied to awall. Fig. 2 is a view in elevation of the device, a different form ofbracket being employed. Fig. 3 is a view in elevation showing the deviceapplied to the ceiling, part of the invention being shown in section.Fig. 4 is a cross-section of the shaft, showing section of the cord andthe screwcontact; and Fig. 5 is a fragmentary crosssection showingbattery.

of the in' In the drawings, A indicates a bracket in which is mounted ashaft B. The ends of said shaft pass through apertures 1 in the bracketand have threaded thereon the nuts 2 for holding the said shaft againstremoval.

On the shaft Bis asleeve (J, of suitable conducting material, and saidsleeve is adapted to fit snugly between the arms or sides of the bracketyet be free to rotate about the shaft B. Approximately centrally of thesleeve is keyed by the pins 3 a ball D. The said ball is formed of twosemicylindrical sections D and D each section having acentrally-hollowed-out portion adapted to register with each other andform achamber E. The outer edge of the section D is provided with anangular seat 4:, in which the angular head 5 on the section D is adaptedto fit, and thereby lock the sections in their assembled position.

Within the compartment E and secured to the sleeve C, and thereforerotatable therewith, is a battery F, which is electrically connected tothe sleeve G by the wires 6. Exterior of and adjacent to both sides ofthe balls are apertures 7 in the sleeve (J, in which the ends of cords Gare adapted to be inserted,

said cords having wires H centrally thereof,

connected at one end to the balls L. Passing through the sleeve Careconnecting-screws J, said screws being adapted to pass through thecoating of the cords and make-contact with the wire or metallic core. Bythis means a direct connection is made between the battery within thechamber E and the balls L, whichin practice are grasped by the operator.

When in use the .ball D is found to be too light, means are providedwhereby additional weight may be added thereto. In the engaging edges ofthe members D and D are registering raceways I and I, which when inapplied position form a course for the reception of shot or otherweights. By this means the ball may be easily adjusted in weight to suitthe operator.

In Fig. 1 the bracket for supporting the device is shown as consistingof four sides with the rear plate of the bracket secured to the wall andthe exerciserheld by the front face; but to permit of the device beingattached either to the floor or ceiling a bracket approximately U-shapedis employed, Figs. 2 with the and 3. This bracket A is provided at itscorners with apertures 8, in which an end of a flexible or otherconnection 9 is adapted to be secured. The opposite end of thisconnection is secured either to the floor or ceiling. In Fig. 3 thedevice is shown as being attached to the ceiling.

In Fig. 2 the cords are illustrated as being oppositely wound upon thesleeve; but, as shown in Fig. 3, the cords may be wound parallel.

The operation of the device is thought to be clearly apparent, and theadvantage of the vibratory sensation exerted by the electricalsource-and connection and the benelit of the electricity absorbed duringthe use of the device will be readily understood by those skilled in theart.

It is to be noted that various changes may be made in the porportionsand details of construction for successfully carrying the invention intopractice without departing from its scope.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. In adevice of the character described, a bracket, a shaft supportedthereby, a sleeve on the shaft, a ball on the sleeve, a source ofelectricity within the ball and in connection sleeve, and pulls on thesleeve and in electrical contact therewith.

2. In a device of the character described, a bracket, a shaft supportedthereby, a sleeve on the shaft, a ball on the sleeve, said ball being insections, a source of electricity within the ball and in connection withthe sleeve, and pulls on the sleeve and in electrical contact therewith.

3. In a device of the character described, a bracket, a shaft therein, asleeve on the shaft, a ball on the sleeve; said ball being in sectionsand means for securing the sections together, a source of electricitywithin the ball and in connection with the sleeve, and pulls on thesleeve and in electrical contact therewith.

4. In a device of the character described, a bracket, a shaft therein, asleeve on the shaft, a ball on the sleeve, means for adjusting theweight of the ball, a source of electricity within' the ball and incontact with the sleeve, and pulls on the sleeve and in electricalcontact therewith.

In testimony whereof I atfix my signature in the presence of twowitnesses this 1st day of August, 1904.
